FNB treats customers like **** and make you pay for services that does not work

If I could give a minus rating I would! My mum has been with FNB for years - the last year has seen the worst service ever. on the 23rd of Jan 20220 her credit card just stopped working, does not decline, just does not work. we ordered a new card, had numerous issues with the delivery of the card and when she finally got is, the card did not work. Needless to say this resulted in many minutes spend on the phone at my mum's expense with no results whatsoever, in fact due to her age she gets treated like a ***** (did you clean the card, did you use the right pin, are you sure you know how to use the card to mention a few) Anyway, so after all this we ordered a new card (once again being charged for it because it is my mum's fault) Still waiting for the new card, all of a sudden my mum's credit card account will not allow her to transact at all on the app or online, keeps on saying "not permitted" So, NO access to her money, NO card that is working and with my mum's age a massive amount of stress and worry - this is so not acceptable - Please can someone contact my mum and sort this out - this is really horrible service and causing a lot of extra strain and expenses for my mum
